Challenges facing the future of Antarctica
August 15, 2012 10:32 AM - British Antarctic Survey
A century ago, Antarctica was one of Earth's last frontiers, but now the continent is under threat from human activity. An international team of experts, including scientists from British Antarctic Survey (BAS), has set out the current and future conservation challenges facing the Antarctic in a Policy Forum article published this week in the journal Science. The team analysed the effectiveness of the existing Antarctic Treaty System for protecting the region from the threats of climate change and, as technology improves, increasing prospects of use of the Antarctic's natural resources.
Costco, the Genuine Retail CSR Leader
August 14, 2012 09:01 AM - Leon Kaye, Triple Pundit
Could Costco possibly be the most genuine leader when it comes to corporate social responsibility (CSR) and governance? Retailers across the country constantly crow about the achievements they have made on a bevy of issues from more sustainable fish (Safeway) to solar installations (Walmart). Other retailers are yanking the chains on pork producers to cease the cruel use of gestation crates and of course just about everyone is on the organic and local produce bandwagon. These shifts in business practices are great news for fish, pigs and of course, the environment and our health. But what about people who work in these stores, who stack, haul and crate the fish, pork and produce, whether they are free range, cruelty-free, duty free, or not?
Record Burmese Python found in the Florida Everglades
August 14, 2012 07:15 AM - Megan Gannon, MSNBC
A double record-setting Burmese python has been found in the Florida Everglades. At 17 feet, 7 inches (5.3 meters) in length, it is the largest snake of its kind found in the state and it was carrying a record 87 eggs. Scientists say the finding highlights how dangerously comfortable the invasive species has become in its new home. "This thing is monstrous, it's about a foot wide," said Kenneth Krysko, of the Florida Museum of Natural History at the University of Florida. "It means these snakes are surviving a long time in the wild, there's nothing stopping them and the native wildlife are in trouble."
Rate of Arctic summer sea ice loss is much greater than predicted
August 13, 2012 01:12 PM - EurActiv
Sea ice in the Arctic is disappearing at a far greater rate than previously expected, according to data from the first purpose-built satellite launched to study the thickness of the Earth's polar caps. Preliminary results from the European Space Agency's CryoSat-2 probe indicate that 900 cubic kilometres of summer sea ice has disappeared from the Arctic ocean over the past year. This rate of loss is 50% higher than most scenarios outlined by polar scientists and suggests that global warming, triggered by rising greenhouse gas emissions, is beginning to have a major impact on the region. In a few years the Arctic ocean could be free of ice in summer, triggering a rush to exploit its fish stocks, oil, minerals and sea routes.
Black Carbon from Slash and Burn Practices Still a Problem in Brazil
August 13, 2012 06:44 AM - Rachel Nuwer, Science
Although nearly 40 years have passed since Brazil banned slash-and-burn practices in its Atlantic Forest, the destruction lingers. New research reveals that charred plant material is leaching out of the soil and into rivers, eventually making its way to the ocean. So much of this "black carbon" is entering the marine ecosystem that it could be hurting ocean life, although further tests will be needed to confirm this possibility. People have used fire to shape Earth's vegetation for millennia. In Brazil's Atlantic Forest, Europeans began burning trees to make way for settlements and agriculture in the 16th century. What once blanketed 1.3 million square kilometers and ranked as one of the world's largest tropical forests had shrunk to 8% of its former size by 1973, when protective laws were put in place.
Extreme Drought Impacting Crop Yields
August 11, 2012 07:32 AM - NBC News wire reports
Federal forecasters are predicting record prices for corn and soybeans, raising fears of a new world food crisis as the worst U.S. drought in half a century continues to punish key farm states. The U.S. Department of Agriculture on Friday said production of U.S. corn and soybeans is expected to be down 17 percent from its forecast last month of nearly 13 billion bushels, and 13 percent lower than last year. It was the second month in a row when the USDA has cut its production estimate. Corn prices briefly surged to a record on the USDA's forecast, but then retreated because the government said demand for the grain would fall due to its soaring cost.
Facing Environmental Issues on the US, Mexico Border
August 9, 2012 11:22 AM - Allison Winter, ENN
From reducing mobile source emissions, to connecting households to drinking water and wastewater services, to clean-up efforts of streams and canals, the United States and Mexico have made a joint effort to protect both human health and the environment in their shared 2,000 mile border region. The bi-national entities along with various stakeholders created the Border 2012 agreement to help identify and control environmental concerns and public health challenges. As the agreement expires this year, a new Border 2020 agreement was renewed and signed today by US EPA Administrator Lisa Jackson and Mexico’s Secretary for the Environment and Natural Resources Juan Elvira Quesada.
U.S. Auto Industry Jobs Up Nearly A Quarter Million Since 2009 - Fuel Efficiency a Key Driver
August 9, 2012 07:09 AM - NRDC
With the launch of new federal vehicle fuel economy rules only about one week away, the American auto industry has grown by nearly a quarter million jobs (236,600) since June 2009 when the auto industry hit bottom, according to a new report available from DrivingGrowth.org. The report from DrivingGrowth.org finds that fuel efficiency is a major factor behind the gains in U.S. auto jobs. A website that tracks the revitalization of the U.S. auto industry, DrivingGrowth.org is sponsored by three leading U.S. environmental organizations: The Natural Resources Defense Council, the National Wildlife Federation, and the Michigan League of Conservation Voters Education Fund. Manufacturing of motor vehicle and parts has grown by 165,100, or 26.4 percent since June 2009. Another 71,500 jobs have been added at U.S. auto dealerships. Automakers, their suppliers and their dealers are now looking ahead to a brighter future after the dark days of the recession.
Extreme heatwaves 50 to 100 times more likely due to climate change
August 6, 2012 08:46 AM - Jeremy Hance, MONGABAY.COM
A recent rise in deadly, debilitating, and expensive heatwaves was caused by climate change, argues a new statistical analysis published in the Proceedings of the National Academy of Sciences (PNAS). Climatologists found that extreme heatwaves have increased by at least 50 times during the last 30 years. The researchers, including James Hansen of NASA, conclude that climate change is the only explanation for such a statistical jump. "This is not a climate model or a prediction but actual observations of weather events and temperatures that have happened," Hansen, a prominent scientist and outspoken climate change activist, wrote in an op-ed in the Washington Post.
BLM Analysis Reveals Massive Potential Damage From Las Vegas Water Grab
August 6, 2012 08:23 AM - Editor, Center for Biological Diversity
LAS VEGAS— The Bureau of Land Management today released its long-anticipated final environmental impact statement for the pipeline right-of-way for the Southern Nevada Water Authority's "groundwater development project." The project envisions unsustainably siphoning more than 37.1 billion gallons of groundwater per year from at least four valleys in central Nevada and pumping it 300 miles to the Las Vegas Valley.
